[Colin McNamara <colin@xxxxxxxxx>]

I am guessing your intent is to determine the maximum available bandwidth and lowest latency (commonly implemented as least hops) path between hosts. In other platforms there is the notion of Cell, Zone, Row, Rack etc where the host that you are running your workload has the topology encoded in the host meta information itself. 

In instances where this is not encoded within some sort of meta of the host either shortest path first or constrained shortest path first can be run to determine the network, topology and either distributed to the nodes. The challenge here is that it is really hard to take into account available bandwidth between nodes vs hops.

Regards,

Colin

Our default will be to start the conversation about HPC features that folks are interested in adding to the Grizzly release. If anyone has any other specific agenda items, they're welcome to propose them.
